Abstract

When the internal combustion engine is made to start moving, the starter motor is made to turn backward along with the crankshaft to bring the piston temporarily back into the exhaust stroke. Thereafter, the starter motor is made to turn forward and the engine is made to start moving with the piston located in the exhaust stroke. After the starter motor is turned backward for time t1 of energization for backward revolution, the crankshaft is made to turn by inertia for time t2 of suspension of energization in order to place the piston in the exhaust stroke. The times t1 and t2 may be selected from a map of duration of energization for backward revolution and a map of duration of suspension of energization respectively or, alternatively, controlled on a feedback basis by determining the rotational speed and the rate of change of the rotational speed and/or the rotational angle of the starter motor from the pulse signal indicating the commutation position. With this arrangement, inertial energy for forward revolution is accumulated in the rotary system of the crankshaft during the exhaust stroke and the intake stroke so that the compression stroke of the piston can be got through by the effect of combining the inertial energy and the rotational energy of the starter motor. Then, the starter motor can be down-sized to reduce its cost. Alternatively, the crankshaft may be turned backward to the explosion stroke to compress the gas in the combustion chamber so that energy for forward revolution is accumulated as a result of the reaction force of the compression. Additionally, when turning forward, the performance of the motor may be selectively utilized, that is, the starter motor may be made to start operating by intensifying the field by means of control magnetic poles and, when the number of revolutions of the motor gets to a predetermined level, the field may be weakened to increase the maximum number of revolutions of the motor.

M432167 contains conductive terminals to form electrical connectors, which can shorten the working hours, reduce the assembly cost, and improve the product yield. In order to achieve the above purpose, this creation is composed of an integrally formed insulating base and a plurality of conductive terminals housed in the insulated base. The front and rear ends of the conductive terminal are respectively provided with a penetrating portion and a welding portion, and the integrally formed insulation A perforation space is provided on one side of the seat body, and a plurality of perforation passages for accommodating the perforation portion are spaced side by side to communicate with each other. The groove and the accommodating groove are used for positioning the welding part, so that the conductive terminal can directly pass into the insulating base when the electrical connector is assembled. [Embodiment] 凊 Refer to the second to fifth figures, it can be clearly seen from the figure that the creation is composed of an insulating base 1 and a plurality of conductive terminals 2, where: The insulating base Zhao 1 is used It is made by injection molding. The insulation base j is provided with a butt space 11 on the front side, and a penetrating space 12 on the other side far from the butt space η. The bottom of the penetrating space 12 is communicated with a plurality of troughs 4 which are staggered back and forth, and a material surface ΐ4ΐ is provided at the opening of the accommodation slot 14, and an extension is provided on the bottom surface of the insulating seat Zhao 1 for positioning. The positioning post η of the circuit board. The conductive terminal 2 has a flat insertion portion 21 ′, and a docking portion 22 is extended at the fold f of the insertion portion 21, and the other end of the end 22 of the lightning guide 9 * 罝 P 21 is extended to have a welding portion twenty three. The wearing part 2] Please see the third circle to the seventh circle away from the butting part. When constructing, the conductive terminal 2 is worn by Λβ91 & 12 penetrates the M butt joint 22, and the insulating base] penetrates into the insertion channel 13 so that the insertion hole is positioned in the insertion channel

It can be clearly seen from the figure that in the figure, this creation is connected, or multi-layered = connected, so that multiple insulating bases 1 are formed side by side to connect their key points. The “missing” can improve the efficiency. The groove 14 was created by the guide to use the insertion channel 13 and the accommodation of the insulating base 1 ^ When the terminal 2 penetrates into the insulating base 1, the conductive portion 2 is formed. The μ 23 is fixed in the insulating base 1, so the insulating base 1 can be integrated. The first figure is a conventional three-dimensional exploded view.

The part 21 and the connection part 22 are exposed to the docking space 11 by the insertion channel 13, and a plurality of accommodations # ua of the conductive terminal 2 are inserted when the insertion channel 13 is placed to accommodate the insertion channel 13 and are formed simultaneously with the insertion part 21 Positioning, and by staggered rows, the ^ _ ^^ of the conductive terminal 2 thin 23 is then formed into a staggered row.
